Jack Nicklaus' caddie and grandson G.T. Nicklaus (R) celebrates after hitting a hole-in-one on the ninth hole. Nicklaus tweeted afterward: "With all due respect to @themasters, allow me to put my 6 Green Jackets in the closet for a moment and say that I don’t know if I have had a more special day on a golf course. To have your grandson make his first hole-in-one on this stage.... WOW!"

Watson smiles after winning the par 3 contest, which he previously won in 1982. Watson won the Masters in 1977 and 1981. He is not competing this year. No Par-3 winner has ever won the Masters in the same year.
